Astronomers used a perhaps unlikely tool to understand what they saw in their historic first image of the Milky Way’s supermassive black hole: a library of computer simulations that mimic the black hole with millions of variations. Taking an image of a black holesuch as Sagittarius A * in the center of our galaxy, with … Read more
This is the first image of Sagittarius A * (Sgr A *), the supermassive black hole at the center of our galaxy, captured by the Event Horizon Telescope (EHT). It is the first direct visual evidence of the presence of this black hole. Credit: EHT Collaboration Astronomers reveal the first image of the[{” attribute=””>black hole … Read more
Fresh off revealing its first image of the black hole at the center of our galaxy, the Event Horizon Telescope is ready to take its next steps by capturing movies of gas flowing turbulently onto a black hole. The two black hole images the Event Horizon Telescope (EHT) has produced so far – that of … Read more
For centuries, black holes were merely theoretically speculative ideas. This tiny sliver of the GOODS-N deep field, imaged with many observatories including Hubble, Spitzer, Chandra, XMM-Newton, Herschel, the VLT and more, contains a seemingly unremarkable red dot. That object, a quasar-galaxy hybrid from just 730 million years after the Big Bang, may be key to … Read more
Sagittarius A *. Credit: EHT Collaboration / ESO. Black holes are among the most profound predictions of Einstein’s theory of general relativity. Originally studied as a mere mathematical consequence of the theory rather than as physically relevant objects, they soon became thought of as generic and sometimes inevitable outcomes of the gravitational collapse that initially … Read more
Credit: ESO / M. Kornmesser. During the first billion years of the universe, winds blown by supermassive black holes at the centers of galaxies were much more frequent and more powerful than those observed in today’s galaxies, some 13 billion years later. Such winds were so mighty that they slowed down the growth of the … Read more

By SETH BORENSTEIN, AP Science Writer WASHINGTON (AP) – The world’s first image of the chaotic supermassive black hole at the center of our Milky Way galaxy does not portray a voracious cosmic destroyer but what astronomers Thursday called a “gentle giant” on a near-starvation diet. Astronomers believe nearly all galaxies, including our own, have … Read more
First image of Sagittarius A *, the black hole at the center of the Milky Way galaxy. Credit: EHT Collaboration. Black holes are invisible by nature. Their pull is inescapable, forever trapping any light that falls into their gravitational abyss. But just beyond a black hole’s point of no return, light persists, and its patterns, … Read more
